through all feed URLs and add missing tags/categories but I'm afraid
the
"I like to read about personal life of people related to FOO" lobby
is

too loud.

This actually seems backwards to me. Blog posts are not a good way to
discuss serious issues relating to Debian, which are much better dealt
with on mailing lists, where tracking a thread and replying to it works
much better. It is rather hard to follow discussions when they are
spread over several people's blogs and in comments to the ones which
allow them, and extremely time-consuming to attempt to reconstruct the
thread of discussion a few weeks or months later, even if all the posts
happen to be still online. And of course you can never be sure if
discussion has progressed further on a blog which you don't read
yourself; when a single blog appears on multiple Planets it's quite
common to see fragments of a discussion appear on it.

So I would suggest instead that material "unrelated to Debian", but
from people within the broad community, is actually by far the best use
for Planet Debian, and that the more relevant posts are to Debian, the
less appropriate they are for Planet.
